Parts of the Diencephalon & cerebellum

Thalamus

Prevents most sensory signals from reaching the cerebrum

Hypothalamus
Involved in the thermoregulation, hunger, thirst, hormone release, heart rate and more

Interthalamic adhesion

Connects talamus

Mammillary body

Involved in olfaction & episodic memory

(Green arrow)

Infundibulum

connects the hypothalamus to the pituitary gland

Pineal body

Produces melatonin ( sleep cycle hormone)

Vermis

The midline structure of the cerebellum

Cerebellar hemisphere (the two lateral divisions of the cerebellum)

coordinate voluntary muscle movements, balance, and motor learning

Folia (the small fold in the cerebellum)

increase its surface area
